Ai Weiwei joins Amnesty writing campaign to support Snowden, others

LONDON (Reuters) - Chinese artist Ai Weiwei has joined an Amnesty International campaign to encourage people to write messages supporting 11 people, including former U.S. National Security Agency contractor Edward Snowden, the rights group said on Friday.

In its "Write for Rights" campaign, Amnesty International is asking supporters to write to authorities to highlight human rights cases. The group said the campaign is focusing on 11 cases this year, including a jailed Egyptian photojournalist as well as Snowden.

Ai, one of China's most high-profile artists and political activists, has created 11 portraits out of Lego for each case.

"For Edward Snowden, we're asking people to write to Barack Obama in the final days of his presidency," Amnesty International campaigner May Carolan said. "Because Barack Obama has a unique opportunity to grant Edward a pardon that will enable him to return to his country as a free man."
